They're Rev crash logs, the actual Windows logs can be accessed from Dr 
Watson (at least in XP, not sure about Vista.) I believe the Rev crash 
logs do show the various machine states as Rev executes commands.

Right, I don't think there's any logging for Linux. I thought you 
mentioned that the crash happened on both Windows and Linux though, and 
I was hoping the Windows logs would give a clue to the problem on both.

I think that's what the Rev logs do mostly, if you have the software to 
read them. But if you have any other logging tools, the more the better. 
Go for it.

Are you by chance working a lot with images? I had a severe series of 
crashes in a current project on both 2.9 and 3.0 which turned out to be 
image-related, particularly when manipulating large images (there's a 
bug report about that.) I sent the team my stack and it blew up for them 
on demand. I have a scripted work-around for my particular situation.

I've forgotten if you said you sent them your stack, but I've found 
that's the most reliable way to get things fixed, especially if the 
crash log is inconclusive.
